    =====================================================================
    
    1. Summary:
    
    Updated kernel packages that fix multiple security issues and several bugs
    are now available for Red Hat Enterprise Linux 6.
    
    The Red Hat Security Response Team has rated this update as having moderate
    security impact. Common Vulnerability Scoring System (CVSS) base scores,
    which give detailed severity ratings, are available for each vulnerability
    from the CVE links in the References section.
    
    2. Relevant releases/architectures:

    Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64
    
    3. Description:
    
    The kernel packages contain the Linux kernel, the core of any Linux
    operating system.
    
    This update fixes the following security issues:
    
    * A use-after-free flaw was found in the Linux kernel's memory management
    subsystem in the way quota handling for huge pages was performed. A local,
    unprivileged user could use this flaw to cause a denial of service or,
    potentially, escalate their privileges. (CVE-2012-2133, Moderate)
    
    * A use-after-free flaw was found in the madvise() system call
    implementation in the Linux kernel. A local, unprivileged user could use
    this flaw to cause a denial of service or, potentially, escalate their
    privileges. (CVE-2012-3511, Moderate)
    
    * It was found that when running a 32-bit binary that uses a large number
    of shared libraries, one of the libraries would always be loaded at a
    predictable address in memory. An attacker could use this flaw to bypass
    the Address Space Layout Randomization (ASLR) security feature.
    (CVE-2012-1568, Low)
    
    * Buffer overflow flaws were found in the udf_load_logicalvol() function
    in the Universal Disk Format (UDF) file system implementation in the Linux
    kernel. An attacker with physical access to a system could use these flaws
    to cause a denial of service or escalate their privileges. (CVE-2012-3400,
    Low)
    
    Red Hat would like to thank Shachar Raindel for reporting CVE-2012-2133.
    
    This update also fixes several bugs. Documentation for these changes will
    be available shortly from the Technical Notes document linked to in the
    References section.
    
    Users should upgrade to these updated packages, which contain backported
    patches to correct these issues, and fix the bugs noted in the Technical
    Notes. The system must be rebooted for this update to take effect.
    
    4. Solution:
    
    Before applying this update, make sure all previously-released errata
    relevant to your system have been applied.
    
    This update is available via the Red Hat Network. Details on how to
    use the Red Hat Network to apply this update are available at
    https://access.redhat.com/knowledge/articles/11258
    
    To install kernel packages manually, use "rpm -ivh [package]". Do not
    use "rpm -Uvh" as that will remove the running kernel binaries from
    your system. You may use "rpm -e" to remove old kernels after
    determining that the new kernel functions properly on your system.
    
    5. Bugs fixed (http://bugzilla.redhat.com/):
    
    804947 - CVE-2012-1568 kernel: execshield: predictable ascii armour base address
    817430 - CVE-2012-2133 kernel: use after free bug in "quota" handling
    843139 - CVE-2012-3400 kernel: udf: buffer overflow when parsing sparing table
    849734 - CVE-2012-3511 kernel: mm: use-after-free in madvise_remove()
    860787 - [xfs/xfstests 273] heavy cp workload hang [rhel-6.3.z]
